摘要： A system and method is provided for scheduling transmissions from a plurality of services operating over a widely distributed communications network. A headend communications device (such as a cable modem termination system) arbitrates bandwidth among a plurality of cable modems configurable for bi-directional communications. The headend grants a bandwidth region to a specified cable modem or assigns contention regions for a group of cable modems. Each cable modem contains a local scheduler that sends requests for bandwidth according to local policies or rules. Upon receipt of a grant from the headend, the local scheduler selects packets to be transmitted to best serve the needs of the services associated with the cable modem. Accordingly, a service requesting bandwidth may not be the service utilizing the grant corresponding to bandwidth request. Nonetheless, the local scheduler manages bandwidth allocation among its local services such that all requesting services eventually receive bandwidth.

摘要： An optical line terminal (OLT) monitors and controls communications with a plurality of optical nodes (ONs), such as optical network units (ONUs) and/or optical network terminators (ONTs), within a passive optical network (PON), such as, but not exclusively, an Ethernet-based passive optical node (EPON). A tagging mechanism is implemented to identify an origin ON that introduces a frame into the PON segment linking the origin ON with the OLT. The origin ON produces a PON tag to associate its identifier (ON_ID) to the frame. The PON tag facilitates filtering and forwarding operations, and enables the physical layer interface (PHY) to the PON segment to emulate a point-to-point and/or shared communications link. The PON tag allows a MAC control layer to create virtual ports to traffic incoming and outgoing optical signals, and supply the virtual ports to a forwarding entity for frame filtering and forwarding. The PON tag also allows an OLT and ON to track the origination and/or destination of a frame within the PON segment, and accept or reject the frame based on the contents of the PON tag.
